Over the past 10 years we've gone from Sal's family project to a global institution reaching 100+ million students annually. And the testimonials we receive every day remind us that our impact isn't just about big numbers — access to free education meaningfully changes the lives of people in all sorts of situations. (In a recent survey, 64% of first generation students at selective colleges said that “Khan Academy has had a meaningful impact on their education”.)

We face intense challenges in providing access to students across the world (think: everything from videos to interactive content, in and out of classrooms, in all the most important languages, on all the most important devices). We use our data to personalize students' learning and continually improve our content. We're trying to build a strong, diverse team — and we need more help.

We've made some great hires off HN and would love to make more. Especially if you're a designer or experienced engineer. Best way to apply is at https://www.khanacademy.org/careers. Mention HN.

What's the best experience you've ever had developing against a third-party API?

I'm an engineer on BloomReach's Platform team and we're always trying to answer that question while we create the interfaces that many of the internet's largest retailers connect against to power their business.

We've recently expanded our presence to Dallas and are actively looking to hire a Full Stack, Frontend, or Product Engineer. This is a full-time, on-site position in a highly visible and impactful role at the company.

You'll be working with all product teams across BloomReach to define, design and develop a modern web api developer console and experience.

If you've ever tried to deconstruct how companies like Stripe, Twilio, Heroku, and Github make their platform pleasant to develop against, you should reach out. Meals on me.

As one of the early hires in the Dallas office, you'll also get to help define the Texas strain of BloomReach's vibrant startup culture.

We're consistently voted one of the best Bay Area companies to work for, and I can safely say we'll be the best in Dallas.

Salary is very competitive and we offer hefty bonus + equity portions as well. We don't have a req on our site, but this Mountain View based opening would be pretty similar (http://bloomreach.com/jobs/?gh_jid=73290).

Upwork is working on revolutionizing how work is done online. Along the way, we're working on challenging engineering problems while working on new features and products to help meet the requirements of our growing community.

My team is looking to hire someone who can come in and help us design and build backend systems (distributed, resilient, scalable etc.). You'll get to work with people from around the world as well as in a cross functional environment (product, UX, marketing and others) and will get to make a meaningful contribution to our platform.

If you're interested, feel free to email me at rmanoch@upwork.com or you can apply to the job directly at https://goo.gl/7Q5H1p (note that in depth knowledge of Java is good to have, but certainly not a requirement).

Twilio is looking to expand its JavaScript SDKs team. Currently, our team works on cutting edge communications SDKs such as Programmable Video (WebRTC video) and Programmable Voice (WebRTC Audio).

We're looking to add another member to the team with a deep core understanding of JavaScript, and a good knowledge of standards. Our primary job responsibility is to create intuitive, simple APIs over fairly complex mechanisms, so experience with designing public APIs is crucial. Any experience with WebRTC is a big plus, but not necessary.

Feel free to send a resume if you have one, however I'd be more interested in seeing code samples (A link to your github, stackoverflow, etc should suffice). Please send your linkedin profile over too, if you have one.

Please DM me here if interested, with your email address and the information above. Looking forward to hearing from you!
